OK - I might ramble a little but bear with me. I question as to why work up a load? I do it, but why. Given any particular rifle, I can purchase factory match ammo, and it will shoot within 1 moa if not better. Why do we need to "work up a load" for our rifles? If I drop say 44 grains of x powder under a xx caliber bullet, fire it and then zero the scope for that combination, it should always shoot at that aim point. I realize there are variations in powder, brass etc., but all things being equal one shot should be the same as the next or else factory ammo would be all over the place.
Match ammo - 5 shots 1 moa. Reloaded ammo, 5 shots should be 1 moa also regardless of what the charge. Increase the charge or change the bullet weight and they should all land in the same area - why don't they? I'm wondering if I'm going through a lot of trouble finding the sweet spot for my 308 all for nothing. 44 to 46 Varget, 150g bullet and they all land within 1 moa, albeit a different aiming point which is understandable, but all groups within 1 moa. so why work up loads?
